Have you created your main frame window? If so you can call GetActiveView on the main frame pointer.

yes, it should be created in the standard initialization code in CMyApp::InitInstance(). But what is the pointer to the main frame window? I tried to use m_pMainWnd, but it has no member function of GetActiveView.

((CFrameWnd*)m_pMainWnd)->GetActiveView()

TrackPopupMenu

I have an icon in the system tray. When I right click the icon I do this:

pPopup->TrackPopupMenu(TPM_LEFTALIGN | TPM_LEFTBUTTON,
	point.x, point.y, AfxGetMainWnd(),NULL);

where pPopup is a pointer to my menu. When I right click it, if you dont want to do anything you would click outside of the popup menu and it dissappears, however it doesnt dissappeat unless you click the mouse outside of the menu then hover the mouse over the menu. How do I fix that?

Try using TPM_RIGHTTBUTTON, or not using TPM_LEFTBUTTON.

Odd...

I just checked MSDN, it gives this little tidbit:

To display a context menu for a notification icon, the current window must be the foreground window before the application calls TrackPopupMenu or TrackPopupMenuEx. Otherwise, the menu will not disappear when the user clicks outside of the menu or the window that created the menu (if it is visible). However, when the current window is the foreground window, the second time this menu is displayed, it displays and then immediately disappears. To correct this, you must force a task switch to the application that called TrackPopupMenu at some time in the near future. This is done by posting a benign message to the window or thread, as shown in the following code sample:

SetForegroundWindow(hDlg);

// Display the menu
TrackPopupMenu(   hSubMenu,
                  TPM_RIGHTBUTTON,
                  pt.x,
                  pt.y,
                  0,
                  hDlg,
                  NULL);

PostMessage(hDlg, WM_NULL, 0, 0);

Have you tried that?

File Associations

Does anybody know how to or even if you can register file associations in VC++.
for example,
when you double click on a .doc, it will open in word.
that kind of stuff, i know you can do it in InstallShield, but is there a way to do it in the code?
Cheers
Dor

Yes you can. You need to set certain registry keys. The details can be found in this link.

If you are using MFC you could look at CWinApp::RegisterShellFileTypes. You may even refer to the code of the function to figure out how it is done.

If you create a MFC SDI or MDI application with the wizard, some time at step 4 (i'm not sure) you can click the advanced button and define custom file format for your application. Then the wizard will crete a REG file in the project directory. You can have a look at it and see how they do it.

Accelerator Keys

I have Added the accelerator keys to a dialog box. When I run the application I don't see the underline under the leter. Except when I hold down the ALT key then its displayed. I am running Windows 2000. I noticed it works fine under Windows ME. Anyone know how to enable this to show always at runtime.

Thanks

this is an option in the OS itself.. go to control panel, display, effects tab, one of the check boxes says 'Hide keyboard navigation indicators until i use the Alt key'

so if they don't show its the settings

hope that helps Smile | :)

ASCII Code

Hello People,

Is there an equivelant function in C++ (or c) to the Visual Basic Function "Asc".

For example, converting a given character to its ASCII code?

In VB: integer = Asc("A")

Thanks,
Frank

int hello = (char)'a';

In C++ you can do mathematical operations on chars, you can say

char b = 123

char b = 'a'

VC project common folder

4-Jun-02 11:47

Just curious...what kind of projects have a "common" folder? if you want to include some static libraries with your project, how do you include them? I amlooking at my project and I don't see a "common" folder, yet that's where it appears that I should be putting my stuff...

any ideas?

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
